Select/Deselect all in Nominal Row Filter Widget

Hi everybody,

I am making use of several Nominal Row Filter Widget nodes one after the other in a workflow (e.g. it starts with a company, continues to department, employee etc…).

It would be very useful if there was a select/deselect all button in the widget for the user. It gets annoying for someone that needs to select every single possibility in the filter to see all data.

Is there such a feature possible somehow in KNIME currently?
Any hints on workarounds are also appreciated.

Thanks in advance & regards,

In both the configure window and the interactive view, the select all is >> or << depending on where you want it to move. Is that what you mean? If not, please share screen shots or a workflow to better help you. Thanks!

Hi Victor,

thanks for the reply.

We are using ‘Checkboxes’ as the type of widget. For those there is no ‘select all’ option.

I tried also what you suggest here, using ‘Twinlist’, and faced another problem: the list gets long if there are many options available. If you configure the min & max height of the widget inside the component, some values are cut off and there is no scroll bar to go down.

I could not find a workaround for this.


Thank you for reporting this, I’ve made an internal ticket to see if we can come up with a solution.
